On the first flight, 3/23/13, moments after lift off, the elevator trim jumped to Full Nose Up. Trim control in the cockpit was non-responsive. I had to hold firm forward pressure on the stick to maintain level flight with the stick position about neutral. The bounced landing bent the nose strut. Investigation after the flight revealed the epoxy seal on the sheath of the Nyrod trim tab rod had broken. The Nyrod center rod and the sheath were not damaged. The break is at the entrance to the horizontal stabilizer leading edge inside the fuselage. This allowed the sheath to move resulting in the trim tab moving to the Full Nose Up position. The fix is to secure the Nyrod sheath. This is the same practical installation requirements for any Bowden cable. NV aero is shipping a new nose strut. Here are some pictures from my website showing the Trim Control in the cockpit at Full Nose Down, the Elevator Trim Tab at Full Nose Up, and the broken Nyrod sheath anchor area:
